I am working on an OpenAPI validation solutions tailored specifically for municipal API deployments and was working with the JSON Schema for version 2.0 of the API specification. I wanted to help make my work be as ready for the future of the API specification and wanted to see if there was a JSON Schema for version 3.0 of the OpenAPI specification. I couldn’t find anything in the new branch of the repository, so I set out seeing if anyone else has been working on it.

I will keep an eye out on the OpenAPI repo for when they add an official JSON Schema for version 3.0. As I’ve learned more about JSON Schema, the more I’m learning about how it helps harmonize and stabilizing tooling being developed around any schema. Without it, you get some pretty unreliable results, but with it, you can achieve some pretty scalable consistency across API tooling and services–something the API space needs as much as it can get in 2017.
